For me, barleywine is the undiscovered country. I generally don't like highly malted beers (they usually strike me as almost sickly sweet), so I'm reluctant to spend the dough on a bomber unless I have a really good sense of what I'm getting into.
That said, I did recently try Flat Tail's Seriously Low Budget Barleywine (because it was priced as such), and liked it. Probably because it was still pretty hop-forward.
